,4 Claims. (Cl. 229-41) The invention relates to improvements in boxesand more especially inboxes made of flexible material such as boxboard,paper, or the like and has for its primary object the provision of aboxconstruction of the character indicated made in two swinging partsand so constructed and arranged as to effect comparatively snug fittingbetween them, the present application being a division of my applicationfiled in the Patent Office on December 12, 1936, Serial No. 115,551.

Other objects will'appear hereinafter.

I he invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by referblank from which the boxis formed;

verging ends I9 for reception of a handle member formed on the other endof the box blank.

The bottom portion II is provided with end walls conneoted by triangularfol'dable flaps 2|, 22 and 23 withthe ends of the side walls I3 as bestshown in Fig. 2. The adjacent corners of the side walls I3 are formedinto locking tongues as shown, said locking tongues being adapted andarranged to be inserted in diagonal slits 24 in the end walls 20 whenthe triangular flaps 2|, 22 and 23 are properly folded for the purpose,thereby serving to secure this edge of each of the side Walls I3 inplace when the box is formed, as, indicated in Fig. 1.

The walls 20 are connected as best indicated in Fig. 2 with the ends ofthe end wall 28 for the inner box member, by folding flaps 28 and 21which serve the same function here as the flaps Fig. 3 a partialperspective view showing the g of the parts as the box is being closed;and

Fig. 4 an end view showing the box in closed condition.

The embodiment of the invention illustrated comprises an integral blankmade of boxboard, paper or the like, having one interior portion I0 setoff by scoring or creases as shown to constitute the top or coverportion of an outer box member. The 'top portion In is connected asindicated with a corresponding bottom portion II by a common wall memberI2 which serves as a swinging connection between the outer and inner boxmembers. The top portion I8 is provided with side walls I3 connected bytriangular flaps I4 and I5 with the end wall 16. In assembling the box,the side walls I3 are first folded inwardly onto the top portion wandthe end wall I6. Th end wall I6 is provided with a securing fiap I]which is folded inwardly onto the flap I5 and secured to the wall I6 bymeans of a central staple or'wire stitch as usual in this form of boxesand as will be readily understood by those skilled in this art.

1 The securing flap ll thus constitutes an ordi-. nary and Well knownform of securing flap cooperating with the corner flaps I4 and I5 forsecuring that end of the outer box member in distended form.

The end wall I6 is provided with a transverse slit I8 having downwardlyand outwardly di- I 4 and IE, but are cut off at their outer corners tofacilitate the more complicated folding manipulation.

A handle flap 29 is formed at the top of the end wall 28 as shown. Thecentral portions 30 of the wall 28 and flap 29 are properly freed andscored as shown that they may be doubled upon each other to form ahandle member insertable through the slot l8 when the box is closed asindicatedin Fig. 1. Securing flap 3| is provided at each side at the topof wall 28 to serve as a means of securing the flaps 26 and 21 indistended form in the usual way.

So much of the box as has already been described is precisely the sameas that disclosed in my said application, Serial No. 115,551 andrequires no further description here.

It is to be noted however, that the scored lines 32 at the ends of theside walls 28, as best shown in Fig. 2, are inwardly inclined resultingin an inward inclination to the wall 28 to facilitate the swinging ofthe wall l8 over the wall 28 and to cause a better fit of the parts whenthe box is made up into the condition shown in Fig. 1.

The better fit thus caused is best illustrated and indicated in Figs.- 3and 4 of the drawing. Fig. 3 shows the positions of the parts during theclosing of the box when the extreme free bottom edge of the swingingcover portion I0 is just about to pass over the free upper edge of thebottom portion II and it will be noted that the arrangement is such thatthe former edge swings in closeproximity to, if not actually touching,the corresponding top dge of the bottom portion. Then as the wall It isforced further downwardly over the wall 28, the lower edge'of the wallI6 is' brought into close contact or association with me bottom of thewall 2 2 so as to leave little if any gap at the point 33 in Fig. 4, aresult also due to the inward inclination of the wall 28. This inwardinclination of the wall 28 should be made to approximate the are or pathon which the wall 16 of the cover portion swings in the closingoperation, which will, of course, vary in diiferent sizes and forms ofboxes, as will be readily understood,

While I have illustrated and described the preferred form ofconstruction for carrying the invention into efiect, this is capable ofvariation and modification without departing from the spirit of theinvention. I therefore do not wish to be limited to the precise detailsdisclosed, but desire to avail myself of such variations andmodifications as fall within the scope of the appended claims.

I claim:

1. A box comprising an outer and inner box member swingingly connectedtogether to cause the outer member to swing over the inner member toclose the box, said outer member being substantially the full height ofand substantially enclosing said inner member, the side of the innermember opposite the swinging connection being inwardly inclined from itsbottom to its top and the corresponding side of the outer member beingsubstantially perpendicular to its top.

2. A box comprising an outer and inner box member swingingly connectedtogether by a common wall to cause the outer member to swing over 'theinner member to close the 'box, said outer member being substantiallythe full height of and substantially enclosing said inner member,

the side of the inner member opposite the swinging connection beinginwardly inclined from its bottom to itstop, and the corresponding sideof the outer member being substantially perpendicular to its top.

3. A box, comprising an outer member including a top and a front side,and an inner member including a bottom and front side, said top andbottom of said members being swingably connected together rearwardly ofsaid sides to permit the swinging of the outer member over the innermember to close the box, said outer member being substantially the fullheight of and substantially enclosing said inner member when the box isclosed, the inner angular relation of said side of said inner member andsaid bottom being less than and the inner angular relation of said sideof said outer member with said top being not less than 90.

4. A box, comprising an outer member including a top and a front side,and an inner member including a bottom and a front side, a common wallswingably connecting said top and bottom together at the rear edgesthereof to permit the swinging of the outer-member over the inner memberto close the box, said outer member being substantially the full heightof and substantially enclosing said inner member when the box is closed,the inner angular relation of said side of said inner member and itsbottom being less than 90, and the inner angular relation of said sideof said outer member with its top being not less than 90.
